  1. Res A Performed By Gemini Solutions, Inc. May 2001

  2. Res A • Tasks: • Create full field model • History match recorded production and pressures • Predict future production for current well

  3. Res A Area Modeled

  4. Res A 37 Top of Structure - Section Modeled

  5. Res A 37 Gross Sand Thickness and Model Grid – aquifer excluded

  6. Ternary Diagram - gas and water 8 Layer Model

  7. History Match

  8. History Match • Assumptions: • Infinite high permeability aquifer down dip • Original oil in place adjusted up to 11.1 MMBO • Original Free Gas in Place = 12 BCF • Adjusted oil zone porosity from 30% to 35%

  9. Vertical Fluid Movement Time Across and Cross Section Down – X direction, on strike

  10. Vertical Fluid Movement Downdip to Updip – Y direction

  11. Vertical Fluid Movement Through producing well – X direction, on strike

  12. Vertical Fluid Movement Through Producing Well – Updip to Downdip

  13. Contour Map Layer 1 – Gas Cap Oil movement into gas cap

  14. Contour Map Layer 2 – Gas Cap Oil movement into gas cap

  15. Contour Map Layer 3 – Oil Zone Water movement into oil zone

  16. Contour Map Layer 4 – Oil Zone Water movement into oil zone

  17. Contour Map Layer 5 – Oil Zone Water movement into oil zone

  18. Contour Map Layer 6 – Oil Zone Water movement into oil zone

  19. Contour Map Layer 7 – Oil Zone Water movement into oil zone

  20. Res A 37 Predictive Run • Remaining oil reserves: • 700 MMBO for 1000 psi flowing bottom hole abandonment

  21. Res A 37 – Yearly Production

  22. Res A 37 • Conclusions • 700 MMBO reserves 1000 psi flowing bottom hole abandonment • 39% ultimate oil recovery factor with current well • Bypassed reserves may exist • significant oil volume may have moved to the gas cap • Quick study possible • < 2 man days

  23. Res A 37 • Recommendations: • Improve water/gas history match further • Explore additional wells to recover bypassed oil in gas cap • Explore possibility that oil in place is higher ( especially in southwest quadrant ) • history match would still be possible • gas and water match could be improved further • new drilling location may be possible
